Abstract
The difference between monarchies and republics stems from the variation in the sources of authority and the nature of leadership transition. However, the similarity lies in the fundamental tasks accomplished by political systems, as they represent the structures and institutions that manage the relationships between the ruler and the governed within the state. These systems are responsible for organizing public life and achieving stability. The core tasks differ according to the nature of the political systems, whether they are monarchies, republics, or (democratic, authoritarian, or others). Each system has its own features and characteristics that impact the state's stability, either positively or negatively.
